CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 501,710, dated July 18, 1893.

Application led April 7, 1893.` Serial No.469,4.13. (No modelJ' i To a/ZZ whom t may concern.:

Be it known that we, HERMANN GAY and FIDELIO FINKE, of the city of Baltimore and State of Maryland, have invented certain Improvements in Car-Couplers of which the following is a specification.

In the description of the said invention which follows, reference is made to `the accompanying drawings forming a part hereof and in which-f Figure l is an under side view of portions of two car bodies provided with our improved couplers, andbefore the same are coupled."

Fig. 2 is a similar view showing the cars coupled. Fig. 3 is a face view of one of the couplers together with a part ofthe car body. Fig. 4 is a side view of a portion of a draw head forming a part of the invention. Fig. 5 illustrates details of the coupler.

Referring to the drawings, A represents the car bodies, and B the drawheads of the couplers.

C C are draw-bars extending rearward from the draw-heads. These draw-bars 'pass through suitable bearing boxes a secured to the under side yof the bodies A of the cars. The draw-heads are adapted to slide in holders D which may be of any suitable construction and shape, and their outward movement is limited by collars b on the drawbars which come in contact with the bearing boxes. l

E E are springs coiled about the draw-bars and extending endwise between the bearing boxes and the rear ends of the draw-heads. These springs yieldingly keep the draw-heads -in their extended position, except when theV cars are coupled. Each draw-head has a notch c in one side, into which the inner` end of a pivoted tumbler F enters when the drawheadsare forced inward as the cars are brought together, and prevents the return of the drawheads to their extended position, until released by means hereinafter described. The tumbler F has a pin d at its outer end which is seated in a slot e in the short arm f of the hand lever G which lever is pivoted to the car body. A spring H of any appropriate construction retains the hand lever Gr yieldingly in such position as will keep the end of the tumbler F in the notch c in the drawq head. From this description it will be understood that when a draw-head is forced inward, it is caught by the tumbler and held until released by the movement of the hand lever in a direction contrary to that autoeye t' similar to those of theV link. The hook 6o VVis much shorter than the link, as shown in the drawings. The link and hook are required to move together, and to accomplish this, the eyes of the said devices are made square and the pivotalbolt j which passes through them is also square and of the same size, see Fig. 5. The lower end of the pivotal bolt j extends below the bottom of the draw-head, and on it is secured anrarm K having a connecting rod Lat its outer end which connects it to a`7o spring M fastened to the platform of the car body. The length ofthe connecting rod L is `such that when the draw-head is depressed or forced inward,'its end strikes the platform `and has the effect of throwing the link I and hook J out from aposition at a right angle with the longitudinal center line of the car, into alignment with that center line, as illustrated in Fig. 2 which shows the cars coupled.

When however the dra'wheads are extended 8o the springs M draw the connecting rod L and arm K in, and the linkI and hook J are forced into the first position described, as shown in Fig. l whichillustrates the cars as not coupled.

Supposing that two cars are to be coupled,

they are brought toward each other, and as the draw-heads comein contact, they are forced inward and held in that position by the tumblers entering the notches. At the same time the links and hooks of the two couplers en- 9o gage with each other and the cars are coupled, as shown in Fig. 2. When the cars are to be uncoupled, the hand levers are moved so as to withdraw the tumblers F from the notches c in the draw-heads, when the springs E force out the draw-heads and the links I and hooks J are detached from each other.

We claim as our invention-f A car coupler having the following elements in combination, viz., a draw-head held yieldroe ingly in an extended position with regard to the car body, and provided with a notch, as described, a tumbler adapted to enter the said lar link and hook on another couplergsubstannotch when tlhe dlaw-head is forced inward, tially as specied. and thereby old t e said draw-head, a springheld lever for operating the said tumbler, and

5 a pvoted link and hook adapted to be thrown into alignment with the longitudinal center Witnesses: line of .the car as vthe .draW-baris depressed,% yJOHN iL. HEBB,

and thereby adapted to couple with Va simi-1 T. HOWARD.
